while with mixed modulation (QPSK-16-QAM), the transmission rate is 24.1 Mbps for the far user (FU) and 48.2 Mbps for the near user (NU). In the case of a three-user PD-NOMA scheme, the maximum ...

This is a high throughput QAM constellation demapper and Log Likelihood Ratio (LLR) bit-metric generator. The core is capable of accepting a new equalised QAM symbol per clock cycle and generates all ...

The algorithm improves the vector-valued phase estimator (VVPE) method by selecting the outermost constellation points to improve the phase estimation accuracy, and it supports various QAM modulation ...

We show how in E – PV – SOM recurrently connected networks an SOM-mediated modulation can lead to simultaneous increases in neuronal gain and network stability. Our work exposes how the impact of a ...

QAM Modulator and Demodulator combine two amplitude modulation signals into a single data transfer channel: 1. Technique of modifying any one characteristic (amplitude, frequency, or phase) of a ...

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of ...
